In N Out Burger

In-N-Out Burger is a hamburger chain in the western United States. The chain's menu features just four basic items -- hamburgers, cheeseburgers, the Double-Double (two patties and two slices of cheese), and French fries -- but patrons are free to customize their hamburgers and add on shakes or sodas. The chain does not use microwaves, heat lamps, or freezers.
